Pixel Intensity Analysis for Digital Image
The problem asks us to count the number of pixels in a given $4 \times 4$ digital image whose intensity value ($U$) is less than or equal to 4. The pixel intensities are provided as:
0, 1, 0, 2, 4, 7, 3, 3, 5, 5, 4, 4, 6, 7, 3, 2
Identify Pixels Satisfying the Condition
We need to find pixels where the intensity '$U \le 4$'. Let's examine each pixel value:
- 0: $0 \le 4$ (Yes)
- 1: $1 \le 4$ (Yes)
- 0: $0 \le 4$ (Yes)
- 2: $2 \le 4$ (Yes)
- 4: $4 \le 4$ (Yes)
- 7: $7 \le 4$ (No)
- 3: $3 \le 4$ (Yes)
- 3: $3 \le 4$ (Yes)
- 5: $5 \le 4$ (No)
- 5: $5 \le 4$ (No)
- 4: $4 \le 4$ (Yes)
- 4: $4 \le 4$ (Yes)
- 6: $6 \le 4$ (No)
- 7: $7 \le 4$ (No)
- 3: $3 \le 4$ (Yes)
- 2: $2 \le 4$ (Yes)
Calculate Total Count
Count the number of pixels identified as satisfying the condition '$U \le 4$'.
The pixels satisfying the condition are: 0, 1, 0, 2, 4, 3, 3, 4, 4, 3, 2.
Total count = 11.
